1) Assume the following summary statistics, which describe the speed of a computer processor, are available from a sample of Intel Pentium IV chips manufactured at the company's Arizona chip plant (values are in Megahertz):
Modal Speed: 3200
Median Speed: 3400
Mean Speed: 3600
S.D. Speed: 100
A. According to these statistics, how are the data distributed (i.e. left skew, normal, right skew)?
B. According to Chebyshev's Theorem, what minimum proportion of processors have speeds between 3400 and 3800?
C. Assume Intel uses the mean speed as the accepted speed of their processors for advertising purposes. Given how the data are distributed, do you believe this could be misleading to P.C. buyers or not?
Whether the suitable analysis would be one-tailed test or two-tailed test. A type I and type II error, given context of hypothesis.
Be sure to specifically identify the statistical formulas and what additional data you would need to determine your estimate(s).
